23S09-1DCG8

Overview

The Renesas Electronics 23S09-1DCG8 is a high-speed phase-locked loop (PLL) clock buffer designed for clock distribution applications. It operates within a frequency range of 10MHz to 133MHz and accepts one reference input to drive two banks of four low-skew clocks. The device achieves zero delay by aligning the phase between the incoming clock and output clock. It features an on-chip PLL with feedback obtained from the CLKOUT pad, eliminating the need for external RC networks. The component supports LVTTL inputs and CMOS/LVTTL outputs, operating at 3.3V with a supply voltage range of 3V to 3.6V.

Feature Summary

• Zero Delay Buffer: Aligns output clock phase with input reference clock using an on-chip PLL.
• High-Speed Operation: Supports frequencies up to 133MHz with low skew characteristics.
• Low Power Consumption: Draws less than 12μA in power-down mode when no input clock is present.
• Flexible Output Configuration: Drives two banks of four outputs with separate output enable controls.

Applications

• High-speed clock distribution systems
• Data communication equipment requiring low jitter
• Embedded systems needing precise clock alignment

Procurement Notes

Verify the specific suffix '8' against official Renesas documentation to confirm packaging details such as tape-and-reel quantity versus tube packaging. Ensure compatibility with RoHS3 standards if required for the target assembly process. Check for any Product Change Notices (PCN) related to assembly sites or material changes before finalizing procurement plans.

Selection Notes

Select this component when a zero-delay buffer with up to nine outputs is required for frequencies up to 133MHz. The -1H variant offers higher drive strength compared to standard versions; verify if the -1DCG8 meets drive requirements. Ensure the application environment falls within the commercial temperature range of 0°C to +70°C unless industrial variants are specified.

Part Context

The 23S09 series belongs to Renesas' FemtoClock family of clock buffers. It is functionally similar to the 23S05 but provides additional outputs. The device is part of a lineage that includes variants like the 2309 and 23S09E, which may differ in temperature ranges or manufacturing status. Always consult the latest datasheet for pinout and electrical specifications.

Replacement Considerations

Renesas recommends the 23S09-1HPGGI8 as a replacement for certain obsolete variants in the 23S09 family. Verify pin-to-pin compatibility and electrical parameters before substituting. Other potential replacements include the 2309-1HDCGI8, though package differences must be accounted for.
